Patent DE-19738357-A1 (DE)
Inventor: SCHMIDT KURT DR
IPC: G06F1/035
Filed: 1997-09-02
Abstract: The invention relates to a digital sine wave generator in which at least one quadrant of the sine is divided into a plurality of segments. One amplitude value corresponding to the amplitude of the sine and one ascent value corresponding to the ascent of the sine are stored in a memory for each supporting position of every segment. The amplitude of the sine to be generated is calculated by means of linear interpolation for more interspaced adjacent intermediate values. An optimized amplitude value is stored as an amplitude value, said optimized amplitude value being smaller than the exact amplitude value of the sine at the supporting position.
